Dont knock the quick epoxy fix. Ive personally done the epoxy thing with a repair that could print a 60% screen on that unit and you couldn't even tell there was a repair. It even lasted close to a year before it began to show some porosity. That fix was a far cry from $1500 bucks. It...

50% of any color, or any substance for that matter can be whatever your unit of measurement is. It can be 50 grams, 50 kilograms, 50 ounces, or 50 tons. If an ink formula calls for 50 percent transparent white then you just need to choose a unit of measurement that gets you were you want to be...

not sure just how much digital printing is affected by lamination, but I can tell you that with sheetfed offset printed sheets that are offline laminated, the sheet grain has a pretty big effect on the curling you describe.

On a modern printing press, and I will just use Heidelberg as an example, only because im most familiar with them, there is a setting in the presses interface called "characteristic curves". This setting is where you go to make the sort of adjustments that you seem to be talking about. What im...

So your saying that this has in the past been a working system that has seemed to drift off of its previous accuracy? If so then you need to think about what has changed that would account for such a drift. One thing that comes to mind is the ink fountains zero set has changed as they often...

I will go out on a limb here and say this.... If the press is as old as you say it is, I seriously doubt that you will benefit all that much from the use of CIP3 data, even if you could import the PDF file into the RIP software. If your thoughts are that by providing the press with the ability...

If a plate is allowed to run for too long with insufficient dampening, so as to run with an inked non image area, it is common for that area to become sensitized and continue to take ink even after damp feed is increased.

late to the party but as long as the Pantone color in question is stand alone, with no overprinting or edge trapping, you will find color to be much more manageable, if the inks were mixed opaque!!!

Considering the wide variations in paper qualities companies choose to print on I can not see a one size fits all solution to this problem.

It is possible to get 19"x25" with the grain oriented in its long direction. As long as youve got a cutter large enough to handle it, you can purchase your stock 38"x50" and quarter it. Using a sharp knife and back trimming all non factory cut edges would of course be a MUST.

My first and best suggestion would be to go with a 5/c press as opposed to a 4/c. The additional unit will ad much flexibility to the process. As far as LED vs Conventional curing I would say that unless your planning to print on non pours substrates like metallic foil and synthetic plastic...

Ive been retired for the last 7 years so Im not sure who is still standing these days.

You can get it both ways.

Are we talking digital or sheetfed? If sheetfed I too would be looking first at the shops climate. You indicate that the RH is well under control. My next thing would be to be sure that the presses de curler if so equipped, was not causing the reverse call. Lastly I would be looking at...

My one and only UV experience was years ago when UV curing on a sheetfed press was in its infancy. What I recall about that experience was that as long as your rich black process builds are set with good UCR curves you could make full stacks in the delivery, with ZERO bricking or setoff issues...

As a 35 plus year sheetfed veteran, your post bring to mind a sad reminder of the direction that our industry has taken. The transition of our industry from a highly skilled trade, with well paid craftsmen, to the fully digital world that replaced it has left many missing the "good ole days"...

Print length should not be an issue as the packing Alibryan suggests is under the blanket. To have an effect on print length the packing change would need to be under the plate on a sheetfed press. Even if there was a change in print length, it would be minor. An additional .004"of packing on...

The reduced thickness of plates brings to mind a few different unsettling possibilities. First off it is NOT consistent with what you agreed upon. Years ago this wouldn't be as much a problem as it is today because you could just make up caliper difference with paper packing. Most modern...

Be sure to also test rub resistance with coating applied as well as without coating.

If UV is not an option,IML will work best with an oxybind or high solids inkset, along with an aqueous coating formulated for non porous substrates.
